Public predicates

parse/2

Parses Base85 (Ascii85) data from the given source (atom(Atom), chars(List), or codes(List)) into a list of bytes.

Compilation flags:
static
Template:
parse(Source,Bytes)
Mode and number of proofs:
parse(++compound,--list(byte)) - one_or_error
Exceptions:
Source is a variable:
instantiation_error
Source is neither a variable nor a valid Base85 source term:
domain_error(base85_source,Source)
Source contains Base85 data with characters outside the Base85 alphabet:
representation_error(base85)

generate/2

Generates Base85 (Ascii85) in the representation specified in the first argument (atom(Atom), chars(List), or codes(List)) for the list of bytes in the second argument.

Compilation flags:
static
Template:
generate(Sink,Bytes)
Mode and number of proofs:
generate(+compound,+list(byte)) - one_or_error
Exceptions:
Sink is a variable:
instantiation_error
Sink is neither a variable nor a valid Base85 sink term:
domain_error(base85_sink,Sink)
